Introduction
This project serves as a reference implementation for a Cloud Native Application using modern Java frameworks. The target cloud environments range from local setups with Minikube and Docker Edge during the development phase, to production setups on the IBM Cloud. Our application also integrates with Istio for service management.
Architecture
Application Overview
This application functions as a storefront featuring a catalog of antique computing devices. Users can search and purchase items in a seamless fashion. Here’s a breakdown of the architecture components:
- Web Application: Built with AngularJS, this serves as the front interface.
- Backend for Frontend (BFF): These Node.js Express Framework based microservices facilitate data interaction.
- Microservices: Deployed inside a Kubernetes cluster, these services fetch data from a range of databases.
- Databases:
- The Catalog service utilizes ElasticSearch
- The Customer service relies on IBM Cloudant
- Inventory and Orders services use MySQL
Implementation
The implementation of the application is underpinned by two powerful frameworks:
Troubleshooting
If you encounter issues during the setup or implementation phases, here are some common troubleshooting tips:
- Deployment Failures: Ensure that your Docker containers are correctly built and labelled.
- Database Connection Issues: Verify the credentials and connection strings for your databases.
- Service Communication Errors: Check your Istio configuration and ensure that services are correctly registered within the mesh.
